Diethylene glycol dibenzoate

Diethylene glycol dibenzoate (CAS 120-55-8), commercially known as Benzo Flex 2-45 and abbreviated as DEGDB, is a benzoate ester plasticizer used in polymer, coating, and adhesive systems.

Where is Diethylene glycol dibenzoate used?

• Polymer matrices: primary or secondary plasticizer improving flexibility and processability
• PVC formulations: effective plasticization with low volatility
• Flooring, wall coverings, and flexible film applications
• Adhesives and sealants: adjusts tack, flow, and open time
• Coatings and printing inks: coalescing aid and film-forming plasticizer improving substrate adhesion and surface finish
• Personal care: plasticizer in nail lacquers and film-forming cosmetic products
• It is effective in both water-based and solvent-based systems.

Good to know: Buyers should confirm grade suitability against specific formulation requirements, particularly where low-color or low-acid-value material is specified.

Commercial specifications

• Clear, pale liquid in drum and IBC quantities
• Purity specifications typically at 99%+
